Foiles new "Strait Pipe" is desinged with an adjustable reed and an end piece that slides off. For the more advanced caller this is a plus to control the backpressure while making those subtle clucks, double clucks and sexy sounds that fool the most educated honkers. The bell design allows the call to operate with no backpressure control-it does it for you-and anyone can blow this call and get realistic honker sounds with a little practice. The included instructional DVD even shows contest flue routines as an added bonus. Jeff takes you step by step instructing you on how to make the "Strait Pipe" a natural sounding, stone cold killer.
